Table 1 shows speciated Hg concentrations in flue gas at each sampling site. More than 99 % of Hg in feed coal released into flue gas. Since Hg existed in form of gaseous Hg° in flue gas above 680℃ (Frandsen et al., 1994), Hg° was the dominate speciation at the outlet of furnace where the temperature was higher than 830℃.As the …

To mitigate global warming, phasing out coal in the global energy system orderly and rapidly is an important near-term strategy. However, the majority of coal-fired plants in China have operated for less than 15 years. Accelerated coal power plant retirements would lead to substantial asset stranding. Coal-to-nuclear (C2N) technology …
